Missing the END:VCARD line or using incorrect line breaks.
Online converters may time out. Use a script or a desktop application (e.g., CSV to VCF converters can also handle JSON with a pivot). For massive conversions, consider splitting the JSON into chunks of 500 contacts.
To understand the conversion process, one must first appreciate the fundamental differences in the philosophy of these two formats. json to vcf converter

You can export contacts from Telegram as JSON and use specific GitHub scripts to convert them for your phone. Missing the END:VCARD line or using incorrect line breaks
Never upload JSON files containing sensitive personal information or proprietary corporate contacts to unverified free online tools. Use local offline scripts for sensitive data. Method 2: Programmatic Conversion Using Python
JSON is a lightweight data-interchange format. It uses key-value pairs and ordered lists. A typical JSON contact object looks like this: For massive conversions, consider splitting the JSON into
| Tool | Platform | Price | Max Contacts | Custom Mapping | Privacy | |------|----------|-------|--------------|----------------|---------| | ConvertJSON2VCF.com | Web | Free | 200 | Yes | Client-side | | JSON to VCF (GitHub gist) | Python script | Free | Unlimited | Full | Local | | EasyContactsConverter | Desktop (Win/Mac) | $29 | Unlimited | Advanced | Local | | Api2Vcf | REST API | Freemium | 10,000/month | Yes | Server-side |
First, ensure you have your data structured correctly. This script processes a local JSON file and outputs a valid vCard file without requiring external libraries.
